Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
No data on phototransformation of the test item are available.
Data on hydrolysis as a function of pH indicate no relevant hydrolysis at environemntally relevant temperatures at neutral (pH 7) or slightly acidic pH. Slow hydrolysis was oberved at pH 9 and 20°C (t1/2 = 44.3 d).
Additional information
The test item showed a slow hydrolysis rate (t1/2 = 44.3 d) for pH 9 at 20 °C, and a moderate hydrolysis rate (2.4 h ≤ t1/2 ≤ 30 d) for pH 9 at 30 and 50 °C. For pH 7 no hydrolysis was observed and therefore a half-life of > 1 year could be assumed for environmentally typical temperatures.
At pH 4 no significant reduction of the test item concentration was observed within the preliminary test and therefore the test item was considered as hydrolytically stable under this condition and a half-life > 1 year could be assumed for environmentally typical temperatures.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
